Comparative efficacy between hemodialysis using super high‐flux dialyzer with hemoperfusion and high‐volume postdilution online hemodiafiltration in removing protein bound and middle molecule uremic toxins: A cross‐over randomized controlled trial

HD + SHF + HP could not provide superior efficacy in removing uremic toxins to high-volume postdilution olHDF. The use of low BFR of 200 ml/min during the first 2 h of HD + SHF + HP session, according to the instruction of manufacturer, might impair the efficacy of the HD + SHF part in removing uremic toxins.
